Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery ...

In 1999, UCLA professor John Miao pioneered a technique called coherent diffractive imaging, or CDI, which allows scientists to re-create the 3D structure of noncrystalline samples or nanocrystals. The achievement was extremely ...

Researchers from the University of Cambridge, together with French collaborators based in Toulouse, have developed a new method to see inside battery-like devices known as supercapacitors at the atomic level. The new method ...

Headlines about a computer's pricetag beyond consumer imaginations have been rolling in this week. They're calling it the Raspberry Pi killer. The crazy-cheap computer. The every-hacker's dream toy. By now you may have seen ...

In a rolling, outdoor field, full of lumps, bumps and uneven terrain, researchers at Oregon State University last week successfully field-tested for the first time the locomotion abilities of a two-legged robot with technology ...

To overcome the danger of fires and increase the energy density of lithium batteries, researchers are developing solid-state lithium batteries that replace flammable liquid electrolytes with a safer solid electrolyte. These ...

When working on a unique lithium-germanide battery with colleagues from the National University of Singapore, scientists at Pacific Northwest National Laboratory encountered a catch-22: They knew an exciting reaction was ...

High above the bustling city of Honolulu, in a quiet, exclusive hillside neighborhood where some of the island's wealthiest residents live, there is an extravagant home that's not quite like the others.

Wearables and IoT gadgets, featuring smart functions in much smaller form factors, pose battery challenges and headaches by their small size. ARM has made moves that might change the story of battery life of many wearables ...

Battery (electricity)

In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type to store chemical energy and to deliver higher voltage or higher current than with single cells.

The battery cells create a voltage difference between the terminals of each cell and hence to its combination in battery. When an external electrical circuit is connected to the battery, then the battery drives electrons through the circuit and electrical work is done. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications, and is now a multi-billion dollar industry.
